Answer:
6 hours.
Step-by-step explanation:
Let t represent time taken by plant 1 in hours to release the waste.
Part of waste released by plant 1 in one hour would be .
We have been given that two chemical plant 1 releases waste twice as fast as plant 2, so time taken by plant 2 to release the waste would be .
Part of waste released by plant 2 in one hour would be .
We are also told that together they fill the tank in 4 hours. So part of tank filled by both plants working together in one hour would be .
Therefore, it will take 6 hours for the faster plant to fill the tank working alone.
$17,550. I think it’s correct because if you multiply 13,000X 0.35% you get 4,550. So I added 13,000+4,450= and got 17,550.
Answer:
x=3 and x=6
Step-by-step explanation:
The zeros of the function are where the graphs cross the x axis
The graph crosses at 3 and 6
x=3 and x=6
The answer is 8+2x
This is because product means<span> the result of multiplying, or an expression that identifies factors to be multiplied. So 8 plus the product of 2 and the variable x this expression is written like this 8+2x.</span>
